WHAT HAS CHANGED

Winter Weather Advisory for the western/southern Adirondacks, western Mohawk Valley and southern Green Mountains was allowed to expire at 1 AM.

KEY MESSAGES

1) Lake effect and upslope snow showers will gradually diminish this morning across the western Adirondacks and southern Green Mountains.

2) A disturbance is expected to bring scattered snow showers Friday night into early Saturday morning.

3) Low chances for light snow Sunday night into early Monday as a coastal low pressure system tracks well south/east of our area off the Atlantic Coast.

DISCUSSION

KEY MESSAGE 1...

Radar and webcams indicating upslope/lake-enhanced snow showers into the parts of the W. Adirondacks and S. Greens, with even scattered flurries south of Albany. These snow showers and flurries will gradually diminish into this morning as inversion heights lower. Since the bulk of accumulating snow has ended, the Winter Weather Advisory was allowed to expire at 1 AM. Any additional accumulations in these areas will be minor < 1". It will still be breezy today (NW winds gusting 20-30 mph at times), but winds will not be as strong as Wed. High temperatures look slightly below normal today (mainly 20s to lower 30s)

KEY MESSAGE 2...

Guidance continues to be in good agreement showing a short wave trough moving through in the fast NW flow regime Fri night into early Sat morning. Increased PoPs above NBM to mention low chances(~30%) for scattered snow showers. A quick dusting to half inch of snow may occur in some areas, but impacts should be limited due to time of day/weekend. Temperatures look to be near normal through the weekend.

KEY MESSAGE 3...

Most deterministic, ensemble and AI guidance indicating a storm system emerging off the SE coast Sun night into early Mon remains too far south/east for any significant impacts in our area. There are a few ensemble members that show the storm tracking close enough to the coast to bring some light snow to parts of our area, thus NBM continues to have 20-30% PoPs which is reasonable given this is still 4-5 days out. The latest probabilistic Winter Storm Severity index indicating only a 10-30% chance of minor impacts at this time.

AVIATION /12Z THURSDAY THROUGH MONDAY/

Through 12z Thursday...VFR conditions prevail across all terminals with the exception of KPSF where lingering light snow showers have forced both MVFR ceilings and visibility. These have stuck around longer than previously expected with weak returns seeming to remain consistent per the latest KENX radar scans so continued these conditions in a TEMPO for the next couple hours. Elsewhere, the previous forecast largely remains on track with KGFL and KPOU looking to remain within VFR thresholds throughout the 12z cycle, KALB developing an MVFR ceiling for a short period this afternoon, and KPSF holding onto MVFR ceilings for the vast majority of the 12z cycle. Winds will remain breezy out of the northwest with sustained speeds ranging from about 7-12 kt and gusts of 20-22 kt at KALB and KPSF.

Outlook...

Friday Night: Low Operational Impact. Slight Chance of SHSN. Saturday: No Operational Impact. NO SIG WX. Saturday Night: No Operational Impact. NO SIG WX. Sunday: No Operational Impact. NO SIG WX. Sunday Night: Low Operational Impact. Slight Chance of SN. Washingtons Birthday: Low Operational Impact. Slight Chance of SN. Monday Night: No Operational Impact. NO SIG WX. Tuesday: No Operational Impact. NO SIG WX.
